Sorry if my english is not the best. So im upgrading my pc, i have 2x4gb ddr3 ram and was thinking of getting two sticks more of the exact same ram. However my original set i bought 3 years ago, will this be a problem?
The exact ram im buying is hyperx fury ddr3 1600mhz.
 


i am buying exactly the same ram. im just wondering if the 3 year gap will make a diffrence.
